Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Antonio, TX
Alcott Chimney Sweep is a San Antonio chimney company that works on the two very different housing stocks this city is made of: pre-1940s masonry chimneys in neighborhoods like King William and Monte Vista, and the thousands of prefabricated and gas-log fireplaces built across the north and west sides since the 1980s. San Antonio’s mild winters mean most fireplaces sit idle for nine or ten months, which changes what we find when we open them up. Moisture, nesting animals, and flue damage accumulate silently, then a blue norther hits and suddenly everyone lights a fire in the same week. We answer every call with a live person, day or night, at (336) 863-3889.
Why San Antonio Homes Are Different
San Antonio sits on the Balcones Escarpment, where Hill Country storm systems funnel intense rainfall straight into the city. A San Antonio chimney spends most of the year exposed to summer heat above 100°F and periodic deluges, not cold-weather use. That makes moisture intrusion and spalling mortar joints the dominant deterioration mechanism here, not creosote buildup the way it is in northern markets. The older homes in King William, Monte Vista, and Mahncke Park were built with soft local limestone and lime mortar that erodes measurably faster than fired brick under flash-flood-level rain and rare but sharp freeze-thaw events. Meanwhile, the vast 1980s through 2000s suburban expansion around Stone Oak, Alamo Ranch, and Helotes leans heavily on prefabricated zero-clearance fireplaces and gas-log inserts, which shifts the service work from creosote removal toward venting integrity and firebox liner inspection. You need a San Antonio chimney company that knows which type of system you actually have, because the failure modes are completely different.
Our Main San Antonio Services
The two calls we get most often in San Antonio are for sweeps after a dormant season and inspections before the first fire of the year, plus steady repair work on gas fireplaces across the northern suburbs.
Chimney Sweep in San Antonio
A San Antonio chimney sweep is different here because of the long idle season. Creosote, the tar-like buildup that causes chimney fires, is rarely the main issue in our market. What we more often remove is what moved in while the fireplace was off: nesting material from squirrels and birds, leaves, dust, and occasionally a dead animal. San Antonio’s dormant season is also when mortar erosion goes unnoticed, so a sweep here is often the first time a homeowner learns their rain cap is missing or their crown is cracked. We show you what we find before recommending anything. Learn more on our Chimney Sweep in San Antonio page.

Chimney Inspection in San Antonio
In a city where fireplaces go unused for ten months and then get asked to perform during a sudden cold snap, a chimney inspection before the first fire of the season is a genuine safety matter, not a routine upsell. Blue norther fronts drop San Antonio temperatures 30 to 40 degrees in hours, and that first burn is when hidden damage becomes visible, or becomes a chimney fire. We inspect firebox liners, mortar joints, caps, and venting on both masonry and prefabricated systems, and we always show you photo or camera evidence of anything we flag. Details are on our Chimney Inspection in San Antonio page.

Gas Fireplace Repair in San Antonio
Gas fireplace repair accounts for a large share of our work in San Antonio, particularly in the 1980s through 2000s subdivisions where builders installed gas-log inserts as standard. The most common failures we see are thermocouple and thermopile wear, clogged burner ports, faulty wall switches, and venting that has separated at a joint. On gas systems we are careful about one thing above all: a venting leak is a carbon monoxide risk, not a cosmetic issue. If we cannot verify the vent path, we say so plainly. Our Gas Fireplace Repair in San Antonio page covers the repair process in detail.

Prices in San Antonio get pushed up most often by two things: access. Steep roofs, tall flues, and tight attic spaces in older homes around Monte Vista and Mahncke Park all add time. And system type: prefabricated units often require specialty parts that cost more than generic masonry components. Before any work starts, you get a written price. You will never open a final invoice with a number you did not already approve.

FAQs About Chimney Company in San Antonio
Most San Antonio appointments are scheduled within a few days, and we maintain daily routing across the north and west sides of the city. When a cold front hits, call volume spikes sharply because so many fireplaces have been dormant for months. We answer live around the clock, and we will give you a straight answer about the next available slot rather than promising a time we cannot hold.
Routine sweeping and inspection do not require a city permit. Structural rebuilds, liner replacements, or anything that alters the firebox or flue system may trigger permit requirements depending on scope. We handle the paperwork on any job that requires it, and we will tell you upfront if your repair falls into that category. You will know before work begins, not after.
Chimney swifts are federally protected migratory birds that reliably nest inside uncapped San Antonio chimneys from roughly April through September. If we confirm an active nest, cleaning and cap installation must legally stop under the Migratory Bird Treaty Act until the birds leave. We schedule around this by booking pre-spring and post-October work when possible. Once the nest is empty, we can sweep and install a cap so the problem does not repeat next year.
If you have not used the fireplace in over a year, schedule an inspection and a sweep together. The inspection tells us what is wrong; the sweep clears the flue so the inspection camera can actually see the liner. If your fireplace is gas and it is misbehaving, that is a repair call, not a sweep. Call (336) 863-3889 and describe what you are seeing. We will tell you which service fits before we ever book the appointment.
